ll nsolv 5-. WELK Filed Dec. 21, 1940 a Ff? ATTORNEY Patented a. 2s, 1941 v UNITED STATES PATENT. OFFICE CARD DELIVER Y APPARATUS of Ohio Application December 21, 1940, Serial No. 371,130

Claims. (01. 271-87) My invention relates to delivery apparatus for machines of the class described in my copending application Serial No. 352,703.

In that application I have described a stop for card counting machines such as described in my copending application Serial No. 286,570 which illustrates and described a machine for counting cards, checks, loose leaves, etc.

This machine is operated at a very high rate of speed counting accurately as high as 50,000 units or cards per hour.

The machine described in the latter application having to handle so many units in one hours time necessarily requires special delivery mechanism since the cards leave the machine at such a high velocity.

In order to receive the cards or other units being counted I devised an auxiliary wooden delivery or stacker roll which is carried by a cross shaft which in turn is .journaled in arms carried by a shaft which is bolted to the side members of the frame of the machine.

Mounted upon the same shaft are deflector horns adapted to be impinged by the cards which then are guided downwardly under the auxiliary stacker roller and intermediate it and the conveyor belt which rotates the roller and carries the cards to a stacker.

It has been found in practice that it is desirable to have a quick and easy adjustment for this delivery mechanism due to varying conditions such as weight of cards or units, size of same and the varying speeds of the machine.

My invention has for its principal object to provide a quick detachable and adjustable means for supporting the stacker roll carrying mechanism.

My means of accomplishing the foregoing objects may be more readily understood by having reference to the accompanying drawings which are hereunto annexed and made a part of this specification in which:

Fig. 1 is a fragmentary top or plan view, showing only a portion of my counting machine;

Fig, 2 is a side elevation of the same; and

Fig. 3 is a perspective detail view showing my improved support.

Similar reference numerals refer to similar parts throughout the entire specification.

As shown in the drawings the cards (not shown) are discharged from the carrying rollers I, since these are fully described in my application and form no part of the present invention, specific description thereof is omitted.

The machine is provided with side frames or panels 2 and 3 which carry the bearings for the various cross shafts. In the rear of the carrying walls is located the stacker roll 4, a shaft 5 is arranged to carry the stacker roll assembly and the deflector horns. This shaft 5 has a pair of collars 8 and 9 slidably mounted on it. One end of arms I0 and II are rigidly attached to the collars 8 and 9. Means should be provided for adjustment of the locations of the collars on the shaft. As shown I employ set screws I2 for that purpose so that if it is desirable to use a wider stacker roll on account of a variation in the size of the cards, the collars 8 and 9 and in turn the arms [0 and H maybe readily adjusted thereto. An axle I3 is mounted in bearings I4 and I5 located in the ends l6 and ll of the arms l0 and The stacker roll 4 which is preferably made of wood is rotatably mounted on the axle l3. Rotation is imparted to the stacker roll I by contact with a conveyor belt l8 which is provided to carry the cards away from the counting machine.

It will be clear from the foregoing description that the stacker roll 4 can be raised or lowered by loosening the set screws l2 so as to adjust the frictional engagement with the conveyor belt l8. Each end of the stacker roll support shaft 5 is mounted in and carried by a metal block l9. These blocks l9 are preferably provided with holes to which are fitted the ends of the shaft 5. They are fixedly secured on the ends of the shaft 5 by means of set screws 20 or in any other suitable and convenient manner. Friction plates 2! and 22 are riveted or welded to the inside of the blocks IS. The lower ends 23 and 24 of these friction plates 2| and 22 are flared outwardly as at 25 clearly seen in Fig. 3. The inner surface of the plates 2| and 22 should be a tight slide fit over the side plates 2' and 3'. The flaring portion 25 being designed to facilitate mounting the stacker roll assembly in position. V Deflector horns 26 and 21 are mounted on and carried by the axle l3 which carries the stacker roll 4. Provision is made for the adjustment of these horns by means of a series of holes 30 near the end of the horns. These holes coinciding with the axle l3, so that by removing the nuts 28 and 29 on the ends of the stacker roll axle l3, the deflector horns 26 and 21 may be removed and the ends of the axle inserted in the hole which will bring the horns to the required elevation.

It will be apparent to persons skilled in the art that I have provided a construction which permits the entire stacker roll assembly, including the deflector horns, to be quickly and easily rev1 5' moved or adjusted longitudinally of the machine withoutfrequiring the use of-any tools at all. -Having described my invention what I regard as new and desireto secure by Letters Patent is:
